Gigabyte GA-81845GV fast power led flashing

[Applebug]

Hello,

I have a GA-81845GV and what has happend is after a HD failure I installed a new 250GB IDE drive,installed XP etc,everything was working fine but now on a full shutdown and startup I get nothing but a fast paced beeping tone combined with the power LED flashing repeditivly,I've also noted the number 16 LED/DIOD on the main board is on.Any ideas as to what went wrong?
